The Contraptions Workshop DLC for Fallout 4 is now inflicting marble madness and related ailments (logic gate fever, armor rack shingles, conveyor belt cholera, etc.) on settlements all across the Commonwealth. The DLC pack rolled out today across all platforms as part of the Fallout 4 Season Pass and on its own for $4.99 / £3.99.

Like the previous Workshop packs, Contraptions expands your building options. In this case, it's all about making new and improved versions of the many wacky devices that Fallout 4 players were already getting up to: think automated loot sorters and coordinated firework launchers for your Minutemen get togethers. And giant ball bearing tracks, because you can't have a Rube Goldberg machine without something round and roll-y.

The season pass will continue with the Fallout Shelter-ish Vault-Tec Workshop pack in July and the new Nuka World theme park / raider camp in August. That's it for Bethesda's Fallout 4 DLC plans, but you can still look forward to years of cross-platform modding.
